Abstract : The variability with averaging interval of four one-hour periods of wind speed and direction data was studied from data collected at two locations 100 feet apart and 14 feet above ground. The variance of the difference of the wind at the two points was computed by three fundamentally different methods. It is concluded that sampling intervals of the order of five to ten minutes are more effective for predicting winds at a point 100 feet from a sensor than are shorter intervals of 12 seconds to one minute.
